[Closed] Specialized BG Pro RBX 3/4 HELP!

Bit of a saga, Last week I bought a £60 pair of specialized bibs. The seams had a boble effect after one ride, So sent them back.

Kindly the LBS swapped them for a £95 pair of Specialized BG Pro RBX Bib 3/4's 🙂 !! top job LBS!

After 1 ride they seem perfectly fine apart from the inner calf on both legs where there is a 1 1/2 inch patch of wear (bobbling). I can only assume its been rubbing on the crank arms... what am I doing wrong here. When I ride my legs dont seem rub. If I carry on riding wearing these there will be holes... not what you expect from £100 Bib Knickers.

Is this normal? or what am I doing wrong?
